Pressure sensors precisions are top of the range precision pressure sensors.

With a standard accuracy of 0.1% and optional accuracy of 0.05%, these pressure sensors are particularly suitable for use in testing or calibration systems. The program - controlled temperature compensation system practically eliminates temperature - related measurement errors in the range 10°C to 60°C.

The front flush pressure diaphragm avoids zones, in which medium could crystallize or residues could form, thus ensuring trouble-free pressure measurement and hygenic cleaning of the pressure sensor.

Their long-term stability, good corrosion resistance, high protection up to max. IP 67 and mechanical load rating are the basis for use in harsh industrial environments.

For special measuring jobs, the zero point and measuring range can be reset with an IBM compatible PC. The software for the collection, storage and output of the measured values is available as an additional option.

The pressure sensors precisions meet the elec-tromagnetic compatibility (EMC) to EN 61326.
